Abstract
Description
- The invention relates to a transmitter for reception of an electric signal from an acoustic drum. The transmitter comprises a vibration-sensitive body, which is designed in such a way that it lies on the drumhead, whose undulation it can acquire and record.
- It is well known to arrange transmitters or microphones on the body of an instrument in order to receive an electric signal which can be used for the activation of synthesizers or for the conversion of MIDI information (Musical Instrument Digital Interface).
- Known transmitters for acoustic drums comprise as a rule a piezoelectric ceramic body, which is attached to the drumhead with a double-sided adhesive tape. The ceramic body exhibits a relatively slight thickness and in general a circular base area. The transmitters usually used acquire waves of the drumhead regardless of their direction. This triggers problems, among other things because rolls on the drumhead in the middle of the drum emit a weak signal amplitude, while rolls near the edge of the drum result in a strong signal amplitude. This is a genuine source of false signals from the transmitter and was the object of electronic corrections in the subsequent amplification circuit. Certainly it was possible in this way to eliminate a great part of the false signals; however this was dependent on the transmitter sensitivity and on the frequency range of the generated signal.
- To prevent the transmitter body from being struck by the drumstick, the body is arranged in great proximity to the edge of the drum. Up until now this has also produced the shortest possible wiring to the required plug and socket device, which up to now has been provided in the form of a separated unit underneath the edge of the drum.
- By means of shaping of the transmitter body area and by means of its decentralized positioning on the drumhead the transmitter reacts sensitively to all the different undulations as the result of a roll on the drumhead. Such a transmitter is also especially sensitive to decentralized rolls and the undulations generated therewith on the drumhead. A transmitter in oblong shape for a drum is well known from WO 90/03639.
- A further transmitter is well known from EP 0 542 706 B1. The vibration-sensitive device of that transmitter is oblong in shape. The longitudinal axis of the vibration-sensitive device points towards the middle of the drumhead.
- Such a transmitter has the following drawback:
-
- The sound level which a drumstick roll carries out on the drum depends on the location at which the drumstick strikes the drumhead. The sound level is higher, the closer the drumroll is to the edge area of the drumhead. This can be extraordinarily unpleasant and impair the playback of compositions.
- The object of the invention is thus to specify a transmitter of the type initially described, which is designed in such a way that the sound level is not influenced by the location at which the drumstick strikes the drumhead.
- The object of the invention is solved by the features of
claim 1. - In the process, the inventor has proceeded from the lesson of EP 0 542 706 B1. Instead of designing the vibration-sensitive device to be oblong, as specified in the aforementioned patent, the inventor selects a completely different shape for this device. Said device is namely of a shape that does not permit the detection of any orientation, and in any event is not “long stretched out”.
- The shape of a segment of a circle has proven to be particularly favorable. In the process the arc of the circle in expedient fashion has the same radius of curvature as the drumhead, so that it can be placed at the border of the drumhead and is snugly fitting. One could also say that the device has the shape of a wedge of pie. The aperture angle of the segment can amount to 90°. Deviations to the top or the bottom are possible. An angle of 70 or 80°, or even of 100 or 110° is conceivable.
- Other configurations also come into consideration, for example an essentially circular configuration. In this case the device should have a projection, which points to the center of the drumhead.
- The invention is explained in detail with the aid of the drawings. The figures show the following:
-
FIG. 1 is a perspective view of an acoustic drum with an attached transmitter as per the present invention; -
FIG. 2 is a perspective view of a transmitter as perFIG. 1 , showed in non-attached state, and -
FIG. 3 is an embodiment of the vibration-sensitive body of the transmitter. -
FIGS. 4 a,4 b, 4 c, 4 d,4 e show variants of vibration-sensitive bodies in a plan view. -
FIG. 1 represents anacoustic drum 1 with atransmitter 2 attached to it. Thetransmitter 2 comprises aholder 3 with ahook 4, which takes hold of theedge 5 of theborder 6 of thedrum 1. Theholder 3 is attached with ascrew 7, which is fastened to theborder 6. Thetransmitter 2 comprises a vibration-sensitive body 8 (FIGS. 2 and 3 ), which is borne by aspring device 9, which presses thebody 8 against thehead 10 of thedrum 1. -
FIG. 2 represents the embodiment of thebody 8 of the invention, as it is currently preferred the most. Theholder 3 exhibits a reversed L-shape, which creates a house-like cover 11, which protrudes from above and chiefly in a plane running parallel to thedrum head 10FIG. 1 ). At the surface of thecover 11, which is directed toward thedrum head 10, the vibration-sensitive body 8 is borne by thespring device 9. In the preferred embodiment thedevice 9 consists of apiece 12, preferably made of hard rubber, which is adhered to the inner surface of thecover 11, which for its part carries acushion 13, which is preferably made of artificial foam, to which the surface of the downward pointing vibration-sensitive body 8 is attached. The attachment takes place preferably by means of adhesion. - The vibration-
sensitive body 8 is connected to theelectrical conductors 15 at its base, said conductors leading to the inside of theholder 3 down to a plug andsocket device 16 at the end of thefoot 17 of theholder 3. - The
cover 11 and thefoot 17 of theholder 3 form thehook 4, whose shape is adapted to the shape of theedge 5 of theborder 6 of thedrum 1. By means of thishook 4 and thescrew 7 theholder 3 is firmly attached to thedrum 1, causing the vibration-sensitive body 8 to fit securely to thedrum head 10. - One can also recognize the shape of the vibration-
sensitive body 8 fromFIGS. 2 and 3 . The body is a segment of a circle in the plan view. It exhibits a tip 8.1. The angle a to the tip amounts in the present case to somewhat less than 90°. The following are possible: 60, 70, 80, 90, 100, 110, 120, 130, 140° with intermediate values. - The chord of the segment is in the preferred case somewhat the same length as each of the two lateral edges of the segment. The tip 8.1 of the segment can also be rounded off or even cut.
- The vibration-
sensitive body 8 is made of a piezoelectric ceramic material, piezoelectric synthetic material or the like. -
FIG. 4 a shows one possible embodiment of a vibration-sensitive body 8 of the invention. - The
body 8 as perFIG. 4 a is at least approximately circular. It exhibits a wart-like projection 8.2. The projection could also be designed as a tip. - In the case of the embodiment as per
FIG. 4 b thebody 8 is designed in the shape of a hatchet. The peripheral edge 8.3 of thebody 8 is circular. It has the same radius of curvature as the drumhead itself. However, deviations from this are also possible. The lateral edges 8.4 and 8.5 are concave in design. Between the two lateral edges 8.4 and 8.5 a wart-like projection 8.2 is formed. Here again, a tip could be here instead of the wart-like projection 8.2. - The embodiment as per
FIG. 4 c corresponds to the embodiment as perFIGS. 2 and 3 . One recognizes a tip 8.1 as well as the two lateral edges 8.4, 8.5 and the peripheral edge 8.3. - In the case of the embodiment as per
FIG. 4 d the vibration-sensitive body 8 has at least approximately the shape of an ellipse. Said ellipse in turn exhibits a wart-like projection 8.2, which is directed toward the center of the drumhead, which is not shown here. The opposing side of the ellipse has a radius of curvature, which approximates the radius of curvature of the drumhead. - In the case of the embodiment as per
FIG. 4 e the vibration-sensitive body 8 has the shape of a rectangle with rounded off corners. Here again the wart-like projection 8.2 is present. - In all of the cases the wart-like projection could also exhibit a tip, which in mounted state points toward the center of the drumhead.
- The basic idea in the case of all of the embodiments shown here 4 a through 4 e consists in the fact that the vibration-
sensitive body 8 in mounted state viewed in radial direction of the drumhead exhibits a smaller or equally large or at the most essentially larger extension than the dimension running vertically or in the peripheral direction of the drumhead.
